1. Introduction
1.1 General Description
The ISO-DA16/DA8 is bus-type isolated 14-bit D/A card for PC/AT compatible
computers. The optical isolation of the ISO-DA16/DA8 can withstand up to 2500Vrms
of common-mode voltage.
The ISO-DA16/DA8 offers 16/8 channel analog output. The voltage output range
can be configured as ±10V, ±5V, 0-10V, 0-5V and the current output can be
configured as 0 to 20mA or 4 to 20 mA.
The board’s innovative design improves on several drawbacks of the conventional
D/A card. These features are as follows:
Trimless, no jumpers, high channel number and high isolation(2500V) design.
All calibrations can be done by software. The calibration data is stored in the
on-board EEPROM.
The power-on value of the analog output can be pre-defined by the user and is
stored in the on-board EEPROM.
Six different configurations: ±10V, ±5V, 0-10V, 0-5V, 0-20mA or 4-20 mA.
Every channel can be programmed as voltage output or current output
All channel configurations can be selected and changed by software. The user
doesn’t have to change any hardware.
All 16 channels can be configured and used in different configurations at the
same time.(for example, channel_0 = ±10V, channel_1 = 4-20mA, channel_2 = 0
to 5V, ….., at the same time)
The onboard machine independent timer can be programmed from 0.1 ms to 100
ms. When the time is up, a hardware signal can be used to interrupt PC.
16 channels D/I can be directly connected to isolated daughter board, DB-16P
16 channels D/O can be directly connected to relay board, DB-16R, DB-24R
All these features are implemented in a small, compact, reliable and half-size
PCB.

1.2 The Block Diagrams
The block diagram of ISO-DA16/DA8 is shown as follows:
Figure 1: The block diagram of ISO_DA16.
The X86 sends one command to the embedded controller through ISA bus. The
embedded controller will auto read and execute this command. The results of this
command will be stored in the internal data memory of the embedded controller,
therefore the X86 can read back and analyze these results through ISA bus.
The X86 site and the analog output site are fully isolated. Therefore noises from
external devices will be isolated from the X86, this will improve the X86’s reliability.
The calibration can be done by software without any hardware trimming. The
X86 will send out the calibration command, the embedded controller will store this
calibration data into EEPROM. After first power-on, the software driver on the X86
site can download this calibration data from EEPROM.
The power-on start-up value of the analog output can be set by software. These
power-on values are also stored in EEPROM. After first power-on, the embedded
controller will load this data automatically and controller the D/A output to their
start-up values. These start-up values programmed to be voltage output or current
output.
The X86 only needs to send out commands, and the embedded controller will
handle the control details.

The ISO-DA16/DA8 provides 16 TTL compatible digital outputs. The low 8 bits are
stored in address BASE. The high 8 bits are stored in address BASE+1. When first
powered-on, all the D/O output latch ports are disabled, therefore all D/O are in
floating state. All D/O will active if any value output to BASE+2, D/O output enables
control register. If these D/O are active, they will active and can’t be disable again. So
only one enabled output is enough.

The onboard machine independent timer can be programmed from 0.1ms to 100ms.
When the time is up, a hardware signal can be used to interrupt PC. This signal will
be active until access to BASE+3, clear interrupt signal register. The J1 will be in NC
position in the factory setting, but the hardware interrupt signal is also active.
Therefore the software will access or read the clear interrupt signal register after the
timer is up.

2.8 Daughter Boards
2.8.1 DB-16P Isolated Input Board
The DB-16P is a 16 channel isolated digital input daughter board. The optically
isolated inputs of the DB-16P consist of a bi-directional optocoupler with a resistor for
current sensing. You can use the DB-16P to sense DC signal from TTL levels up to
24V or use the DB-16P to sense a wide range of AC signals. You can use this board
to isolate the computer from large common-mode voltage, ground loops and transient
voltage spikes that often occur in industrial environments.

2.8.2 DB-16R Relay Board
The DB-16R 16 channel relay output board consists of 16 form C relays for
efficient switching of loads by programmed control. It is connector and functionally
compatible with 785 series board but with industrial type terminal blocks. The relay
are energized by applying a 5 volt signal to the appropriate relay channel on the
20-pin flat connector. There are 16 enunciator LEDs for each relay, light when their
associated relay is activated. To avoid overloading your PC’s power supply, this
board provides a screw terminal for external power supply.

relay is energized by applying a 5 volt signal to the appropriate relay channel on the
20-pin flat cable connector(just using 16 relays) or an 50-pin flat cable
connector.(OPTO-22 compatible, for DIO-24 series). Twenty-four enunciator LEDs,
one for each relay, light when their associated relay is activated. To avoid overloading
your PC’s power supply, this board needs a +12VDC or +24VDC external power
supply.
